I was working in a large back garden today. The garden shed was connected to an old caravan supply (caravan gone) and the underground S.W.A. cable from the house had been converted to TT earthing originally for the caravan and now for the shed sockets and lighting. As an earth electrode somebody had used a length of 10mm galvanised threaded rod (studding). What are your views about its suitability please?
